* test(#2639): add regression for local-ahead-of-origin warning in handle_branching execute-phase.md's handle_branching forks from origin/$DEFAULT_BRANCH. When local is ahead (unpushed commits), the phase branch silently misses them. The test asserts the workflow checks for local-ahead-of-origin and warns. * fix(#2639): warn when local is ahead of origin before forking phase branch handle_branching forks the phase branch from origin/$DEFAULT_BRANCH. When local $DEFAULT_BRANCH is ahead (unpushed commits like plan/research docs), the fork silently misses those commits. Now a loud WARNING is printed to stderr naming the commit count and advising the user, matching the existing uncommitted-changes warning pattern. * chore(#2639): add changeset fragment * fix(#2639): condense warning under ADR-857 cap + merge emitted-drift ack gsd-test gate caught: (1) execute-phase.md exceeded the 93600-byte Phase 6 ceiling — condensed the WARNING from 3 echo lines to 1. (2) emitted-attribution flagged the growth without an ack — merged into the existing #2930 ack fragment (execute-phase.md was already acked there; can't have two acks for the same path). * fix(#2639): condense warning further to clear the 93400 comfortable-margin gate The ADR-857 Phase 6 test has two assertions: <93600 (hard ceiling) and <=93400 (comfortable margin). Condensed from 3 lines to 2 to fit under 93400 (now 93369). * chore(#2639): backfill changeset PR number 2981 --------- Co-authored-by: sim <sim@local>
GSD Core
Git. Ship. Done.

A light-weight meta-prompting, context engineering, and spec-driven development system for Claude Code, OpenCode, Antigravity CLI, Kimi CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more.
What is GSD Core
GSD Core is a context-engineering and spec-driven development framework that drives AI coding agents (Claude Code, Codex, Antigravity CLI, Kimi CLI, Copilot, Cursor, and more) through a disciplined phase loop. It solves context rot — the quality degradation that accumulates as an AI fills its context window — by running all heavy research, planning, and execution work in fresh-context subagents while keeping your main session lean.
How it works
Each milestone repeats the same five-step loop, one phase at a time:
- Discuss — capture implementation decisions before anything is planned
- Plan — research, decompose, and verify the plan fits a fresh context window
- Execute — run plans in parallel waves; each executor starts with a clean 200k-token context
- Verify — walk through what was built; diagnose and fix before declaring done
- Ship — create the PR, archive the phase, repeat for the next one
Quickstart
npx @opengsd/gsd-core@latest
The installer prompts for your runtime (Claude Code, OpenCode, Antigravity CLI, Kimi CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more) and whether to install globally or locally. The installer is required for cross-runtime compatibility — do not copy files from agents/ or commands/ directly.
On another runtime or without Node.js? See Install on your runtime.
Once installed, start a new project or onboard an existing repo:
/gsd-new-project # greenfield project
/gsd-onboard # existing codebase
New here? Follow Your first project for a guided walkthrough from install to first shipped phase, or Onboarding an existing codebase for brownfield setup.

Why it works
Most AI-coding setups fail at scale because context bloat silently degrades output quality, there is no shared memory between sessions, and nothing verifies that code actually works. GSD Core solves all three: heavy work runs in fresh subagents, structured artifacts like STATE.md and CONTEXT.md survive session boundaries, and the verify step walks through what was built and generates fix plans before a phase is declared done. See docs/explanation/context-engineering.md for the full reasoning.
